Title: Characteristics of the MBE1 End-Station at PNC/XOR

Abstract

An end-station for in-situ characterization of thin films at the PNC/XOR undulator beamline, Sector 20 of the Advanced Photon Source, is detailed. The ability to study films in-situ on a beamline enables examination of surfaces and interfaces on freshly-prepared films, without the influence of a capping layer. The MBE1 molecular beam epitaxy system was designed with this in mind. Now in routine operation and available for General Users on a collaborative basis, the primary function of MBE1 is to undertake polarization-dependent XAFS studies on fresh or stored films, but it also has the capability to do X-ray Standing Wave and Reflectivity measurements. The characteristics of the MBE1 system - its ranges of motions and detector options - are described in detail, with example data illustrating its functionality.

  • The X-ray microprobe is the most popular experimental setup at the PNC/XOR insertion device beamline located at sector 20 at the Advanced Photon Source. To satisfy user demand and to simplify the setup, we have developed a dedicated station with multiple detection options. This paper will describe the setup in detail and demonstrate the capabilities with some example imaging, micro-XAS and microdiffraction data. In the future, an improved version of the microprobe will be installed on a dedicated undulator. The improvements planned for this station are based on our operational experience and will also be discussed.

  • The CEBAF End Station Helium Refrigerator (ESR) System provides refrigeration at 80 K, 20 K and 4.5 K to three End Station experimental halls. The facility consists of a two stage helium screw compressor system, 4.5 K refrigerator, cryogen distribution valve box, and transfer lines to the individual experimental halls. The 4.5 K cold box and compressors were originally part of the ESCAR 1500 W, 4 K refrigeration system at Lawrence Berkeley Laboratory which was first commissioned in 1977. The compressors, 4.5 K cold box, and control system design were modified to adapt the plant for the requirements of themore » CEBAF experimental halls. Additional subsystems of cryogen distribution, transfer lines, warm gas management, and computer control interface were added. This paper describes the major plant subsystems, modifications, operational experiences and performance.« less
